Currently, nearly 3.8 million tons of distillers dry grains are created in domestic dry grind ethanol production. For every bushel of corn made
into ethanol, 18 pounds of DDGS. The potential supply of DDGS is almost 7 million tons.
The corn kernel is mostly starch at 61% of the wet weight, with protein, fiber, corn oil and water making up the remaining 39%. The dry grind ethanol process uses most of the starch present in the corn kernel during ethanol fermentation, leaving protein, fat, minerals and vitamins behind in a concentrated form. The forms of this ethanol co-product are Corn Distillers Dried Grains (DDG), Corn Condensed Distillers Solubles (CDS), Corn Distillers Dried Grains/ Solubles (DDGS), and Wet Distillers Grains with solubles (WDGS).
Because ethanol's co-products, namely distillers grains and corn gluten, are produced in the heart of the U.S. corn and livestock production region, they are readily available and are usually a competitively priced feed ingredient for livestock and poultry diets.
This section provides details about the co-products of ethanol production
